The main body of swivel and cross thermostatic concealed shower valve uses HPb59-1(grade A brass).
Zinc alloy made faucet handwhell is anti-oxidation and corrosion-resistant.
The HPb59-1 panel is anti-oxidation and corrosion-resistant.
The thermostatic cartridge is made of copper to keep being oxidation-resistant and corrosion-resistant.
1. The optimum working pressure is 0.5-5Bar, we suggest a pressure-increasing valve be installed when the pressure is lower than 0.5Bar.
2.The outlet temperature of the cold water is 4℃-25℃and the hot water is 55℃-85℃.
3.The safety temperature is set at 38℃±2℃.
4.Anti-scald: When the cold water is shut down, during the first 5 seconds (±0.5 seconds) if the outlet water volume is less than 200ml, the outlet temperature is within 49℃, otherwise the temperature should be less than 42℃ and the volume less than 300ml, the temperature less than 49℃ in the following 30seconds. Besides, the temperature difference between the outlet water and the set temperature should be within 2℃.
5. Stable outlet water temperature: when the inlet water temperature is stable and the inlet pressure is 0.3 MPa then either pressure of the cold or hot water reduces to 20%; or when the inlet pressure is 0.3 Mpa, the inlet temperature of hot water varies by 10%, eventually the outlet water temperature difference is within 2 ℃ compared with the set temperature.
